2 Printing Ink Printing Ink -- Its Purposes & Functions n Functions Ø Convey a message. Ø Provide protection. Ø Provide colour and decoration that attracts the attention of the consumer Ø Help to differentiate a product from other brands. n Colour is a useful vehicle for emotional selling, play gimmick effects in order to increase the product s attractiveness. n The first impression about a product on the shelf depends on its print appearance on the label that comes from ink. 2

3 Printing Ink Printing Ink - A complex mixture of liquid or paste with colourants dissolved (dye) or suspended (pigment) in it, formulated to transfer and reproduce an image from a printing surface. Printing inks are normally make of the followings; * Colourants - pigments, dyes, and extenders. * Binding agents or varnishes - resin or resin solution. (natural and/or synthetic), plasticiser, etc. * Oil and solvents - Vegetable oil, mineral oil, solvents, etc. * Additives - Wax, stabiliser, catalyses such as photoinitiator, driers, cross-linkers, etc, defoamers, wetting agent, lubricants, etc. The nature of a printing ink is determined by the printing process as well as chemistry of the ink. 3

4 Introduction Different ink types, composition and drying 4 main types of printing ink n Oil based (conventional offset) n UV n Water based (liquid) n Solvent based (liquid) Conventional Offset UV Water based Solvent based UV WATER SOLVENTS MINERAL OILS WATER SOLVENTS 100% DRY RESINS + OXIDIZABLE COMPONENTS DRIED FILM OLIGOMERS MONOMERS + PHOTO- INIITIATOR DRIED FILM RESINS DRIED FILM RESINS DRIED FILM Filtration Several hours Fraction of a second Penetration (paper ) 4

6 Flexo printing, Anilox & HD Flexo 6

7 Flexo printing FLEXO PRINTING a method of direct rotary printing that uses relief image plates of rubber or photo-polymer material Anilox roll is a precision liquid metering device. Precisely controls volume of ink delivered. ANILOX CELL 7

8 Example of Anilox APEX Unifli GTT n New innovation of surface geometry for anilox. n Excellent ink transfer vs conventional aniloxes, avoid spitting, excellent density. n Ideally suited for High Definition Flexography!

9 HD Flexo at a glance v HD Flexo is a new standard with which flexographic printing is raised to the quality of offset and rotogravure. v HD Flexo combines a high-resolution appearance of 4,000 dpi (conventional is ~2540 dpi) with unique anilox technology, thereby achieving Ø higher image definition Ø greater colour space, more contrast Ø better ink transfer. Ø Possible to use finer anilox rollers Ø Can reproduce the entire tonal range of offset print Ø achieve larger print runs. v A steadily growing number of label and packaging specialists are working with this standardized pre-press.
